Aphelion

Aphelion is a high-performance, Rust-native synthetic data generator designed specifically for PostgreSQL and MySQL databases. Unlike other tools that require manual configuration, Aphelion automatically introspects your database schema, resolves complex foreign key dependencies (including circular references), and generates realistic, constraint-safe test data in seconds.

How it works:

• Introspect: Connects to your DB to learn the schema.
• Plan: Builds a dependency graph to strictly order inserts.
• Generate: Creates and inserts data in parallel.

Why use Aphelion?

• Speed: Written in Rust, it generates 10,000+ rows/second.
• Accuracy: Guarantees 100% foreign key integrity.
• Coverage: Supports 80+ exotic types (PostGIS, ltree, JSON).
• Compliance: Generates HIPAA and GDPR-safe synthetic data locally.
